DETAILED DESCRIPTION

The present disclosure is further described below in detail in conjunction with the drawings and embodiments. It is to be understood that the embodiments described herein are merely intended to explain the present disclosure and are not intended to limit the present disclosure. Additionally, it should be noted that for ease of description, only the part, instead of all, related to the present disclosure is illustrated in the drawings.

FIG. 1 is a structural view of a display panel in the related art. In one embodiment, FIG. 1 illustrates a film structure of an organic light-emitting display panel integrated with a touch function. The touch function may be implemented through the principle of TP on the TFE (TPOT). As shown in FIG. 1, the display panel includes a driver circuit layer 12′, an anode layer 15′, an organic light-emitting layer 151′, a cathode layer 152′ and an encapsulation layer 19′ which are sequentially disposed on a substrate 11′. A touch circuit layer 21′ is formed by directly using the encapsulation layer 19′ as a substrate. The touch circuit layer 21′ includes at least one layer of touch electrodes to implement the touch function, and the touch circuit layer 21′ may further be provided with structures such as a polarizer 20′. However, in the process of implementing the disclosure, it is found that the above film structure is complex in wiring and occupies a large space, bringing a poor experience to a user. An embodiment of the present disclosure provides a display panel. The display panel includes a substrate, a drive module layer, a planarization layer, an anode layer, an organic light-emitting layer, a cathode layer and an auxiliary connection line.

The drive module layer, the planarization layer, the anode layer, the organic light-emitting layer and the cathode layer are sequentially disposed on the substrate. The drive module layer is provided with multiple drive modules; and the anode layer includes multiple blocky anodes.

On a plane parallel to a plane where the substrate is located, the auxiliary connection line is disposed in a gap region between adjacent two blocky anodes and is insulated from the adjacent two blocky anodes.

At least one jumper layer is disposed between the drive module layer and the planarization layer. The jumper layer is disposed on a side of the auxiliary connection line close to the substrate; the jumper layer includes multiple jumper portions; the blocky anode is electrically connected to a drive module corresponding to the blocky anode through one jumper portion.

On the plane parallel to the plane where the substrate is located, the auxiliary connection line at least partially overlaps the multiple jumper portions.

In the present disclosure, a display panel includes a drive module layer, a planarization layer, an anode layer, an organic light-emitting layer and a cathode layer which are sequentially disposed on a substrate. The drive module layer is provided with multiple drive modules; and the anode layer is provided with blocky anodes corresponding to the drive modules. The display panel is further provided with an auxiliary connection line which is insulated from the blocky anodes. In addition, at least one jumper layer is disposed between the drive module layer and the planarization layer, so that the blocky anode is electrically connected to a drive module corresponding to the blocky anode through one jumper portion. On a plane where the substrate is located, the auxiliary connection line at least partially overlaps the multiple jumper portions. Therefore, through the bridging between film layers achieved by the jumper portions, the area of a connection portion for connecting a blocky anode and a drive module can be reduced, which is conducive to increasing the width of a gap region between blocky anodes, saving space for the layout of the auxiliary connection line, and preventing the problem that the gap region is too narrow to dispose the auxiliary connection line. In this way, the width of the auxiliary connection line may be set to be slightly wider, so that the difficulty of the process of disposing the auxiliary connection line is reduced, the process of manufacturing the display panel is accelerated, and the manufacturing quality of the display panel is improved.

FIG. 2 is a structural view of a display panel according to an embodiment of the present disclosure. As shown in FIG. 2, a display panel includes a substrate 11 and a drive module layer 12, a planarization layer 14, an anode layer 15, an organic light-emitting layer 151 and a cathode layer 152 which are sequentially disposed on the substrate 11. The stacked structure formed by the anode layer 15, the organic light-emitting layer 151 and the cathode layer 152 may form an OLED light-emitting structure to emit light required for display. In one embodiment, the anode layer 15 includes multiple discrete blocky anodes 15 b, and all of the blocky anodes 15 b are stacked with the organic light-emitting layer 151 and the cathode layer 152 to form multiple discrete subpixels 153. The drive module layer 12 is provided with multiple drive modules 120, and the drive modules 120 may be disposed in correspondence to the subpixels 153. In an embodiment, the drive modules 120 are disposed in one-to-one correspondence the subpixels 153, and the drive module 120 transmits an anode voltage to the corresponding blocky anode 15 b to drive the subpixel 153 to emit light.

In the present disclosure, the display panel may further be provided with an auxiliary connection line 15 a. Referring to FIG. 3, FIG. 3 is a top structural view of a display panel according to an embodiment of the present disclosure. The display panel includes the auxiliary connection line 15 a. On a plane parallel to a plane where the substrate 11 is located, the auxiliary connection line 15 a is disposed in a gap region dl between adjacent two blocky anodes 15 b and is not connected to the blocky anodes 15 b. That is, the auxiliary connection line 15 a is disposed insulated from adjacent blocky anodes 15 b. Referring to FIG. 4, FIG. 4 is a structural view of a comparative example of a display panel according to an embodiment of the present disclosure. Since the comparative example shown in FIG. 4 is not provided with an auxiliary connection line, in order to connect the blocky anode 15 b′ and the corresponding drive module, a relatively long connection portion 151 b′ needs to be disposed in the gap region between the blocky anodes 15 b′, so that the width of the gap region is relatively small, and thus it is difficult to dispose the connection portion 151 b′.

Referring to FIG. 2 and FIG. 3, at least one jumper layer 13 may further be disposed between the drive module layer 14 and the planarization layer 12. Since the auxiliary connection line 15 a needs to be disposed between adjacent blocky anodes 15 b, it is necessary to reserve a relatively wide range for the gap region dl between adjacent blocky anodes 15 b for ease of disposing the auxiliary connection line 15 a. In the embodiment, the auxiliary connection line 15 a and the blocky anodes 15 b may be disposed in a same layer as shown in FIG. 2, or the auxiliary connection line 15 a and the blocky anodes 15 b may be disposed in different layers, as long as it is ensured that the auxiliary connection line 15 a is disposed in the gap region between adjacent two blocky anodes 15 b on the plane parallel to the plane where the substrate 11 is located and does not block the area directly facing the blocky anode 15 b and the cathode layer. In this embodiment, the auxiliary connection line 15 a may be an information transmission line, for example, a signal line through which a driver circuit transmits an initialization signal, a reset and a fixed signal, or a signal line to be in parallel with other signal lines to reduce resistance. Further, the auxiliary connection line 15 a is disposed to form capacitance between the cathode layer and the auxiliary connection line 15 a to maintain a stable potential of the cathode layer, so that the auxiliary connection line 15 a should be disposed as close to the cathode layer as possible. The auxiliary connection line 15 a may be disposed in the anode layer and is disposed in a same layer as the blocky anodes 15 b, or the auxiliary connection line 15 a may be disposed on a side of the anode layer close to the cathode layer, enhancing the effect of stabilizing the potential on the cathode layer by the auxiliary connection line 15 a and improving the stability of a display picture of the display panel.

In an embodiment, the organic light-emitting display panel in the embodiment may be integrated with a touch function, for example, a touch electrode layer may be disposed. The touch electrode layer may be embedded in the organic light-emitting display panel or may be disposed on a display side of the organic light-emitting display panel, and the position at which the touch electrode layer is disposed is not limited in the embodiment. A cathode of a display panel is always on to stabilize a low potential. The cathode is easily to produce potential fluctuations due to a current when the organic light-emitting layer emits light, causing the problem of instability of the cathode potential. Moreover, parasitic capacitance may be produced between the touch electrode layer and the cathode with unstable potential, which easily affects the touch performance of a touch anode layer. According to the embodiment, on the plane where the substrate is located, the auxiliary connection line is disposed in the gap region between adjacent blocky anodes, capacitance is formed between the auxiliary connection line and the cathode layer, so that the potential of the cathode layer is stabilized, and the problem of unstable cathode potential caused by a current between the anode and the cathode is effectively avoided. Therefore, the brightness of the display panel is kept stable, and the display quality of the display panel is improved.

In an embodiment, the material of the auxiliary connection line 15 a may generally include at least one of indium tin oxide or silver. However, for the above materials, a relatively small line width is technically difficult to achieve. Therefore, if the pixel density is relatively large, a relatively large process risk is easily to occur. For example, it is easily to cause a problem that the auxiliary connection line 15 a cannot be connected or is easily broken due to a relatively small line width. On this basis, in order to maintain a high pixel density on the display panel and to ensure that a relatively wide range is reserved for the gap region dl, at least one jumper layer 13 may be disposed on a side of the auxiliary connection line 15 a close to the substrate 11. The jumper layer 13 includes multiple jumper portions 131, and a blocky anode 15 b is electrically connected to a drive module 120 corresponding to the blocky anode 15 b through one jumper portion 131, so that the setting of a connection portion 151 b extending from the blocky anode 15 b is reduced (in the embodiment, the blocky anode 15 b may include an anode body and a connection portion 151 b extending from the anode body), and thus the connection portion 151 b is prevented from occupying too much space of the gap region dl. In an embodiment, on the plane parallel to the plane where the substrate 11 is located, the auxiliary connection line 15 a at least partially overlaps the multiple jumper portions 131. As shown in FIG. 5, FIG. 5 is an enlarged structural view of a local region A1 of the display panel in FIG. 3. An overlapped region exists between the auxiliary connection line 15 a and the jumper portion 131, thus the connection portion 151 b of the blocky anode 15 b does not need to extend to the position at which the drive module is disposed, which is conductive to increasing the width of the gap region dl between blocky anodes 15 b to implement the layout of the auxiliary connection line 15 a, and preventing the problem that the gap region dl is too narrow to dispose the auxiliary connection line. In this way, the width of the auxiliary connection line 15 a may be set to be slightly wider, so that the difficulty of the process of disposing the auxiliary connection line 15 a is reduced, the process of manufacturing the display panel is accelerated, and the manufacturing quality of the display panel is improved. FIG. 6 is a top structural view of a comparative example of a display panel according to an embodiment of the present disclosure. In the comparative example, the above auxiliary connection line is not disposed, the drive modules are disposed in a matrix, and the blocky anodes 15 b may be disposed in many different modes. For example, as shown in FIG. 6, the blocky anodes 15 b′ may be disposed in a triangle mode, so that part of the blocky anodes 15 b′ need to be provided with long connection portions 151 b′ for being connected to the corresponding drive modules. Therefore, a large space of the gap region dl′ is occupied, the auxiliary connection line 15 a′ cannot be set to a relatively large width, and thus the process risk is relatively large.

The drive module layer includes a driver circuit formed by multiple metal layers and insulating layers. In an embodiment, with continued reference to FIG. 2, the drive module layer 12 includes: an active layer 122 disposed on the substrate 11; a gate electrode insulating layer 123 disposed on a side of the active layer 122 facing away from the substrate 11; a gate electrode layer 124 which is disposed on a side of the gate electrode insulating layer 123 facing away from the substrate 11 and is provided with a first capacitive electrode and a gate electrode of a drive module; a capacitive dielectric layer 125 disposed on a side of the gate electrode layer 124 facing away from the substrate 11; a capacitive electrode layer 126 which is disposed on a side of the capacitive dielectric layer 125 facing away from the substrate 11 and is provided with a second capacitive electrode; an interlayer insulating layer 127 disposed on a side of the capacitive electrode layer 126 facing away from the substrate 11; a source-drain electrode layer 128 which is disposed on a side of the interlayer insulating layer 127 facing away from the substrate 11 and is provided with a source electrode 1201 and drain electrode 1202 of the drive module 120; and a passivation layer 129 disposed on a side of the source-drain electrode layer 128 facing away from the substrate 11. In addition, a buffer layer 121 and the like may further be disposed between the substrate 11 and the active layer 122, or the drive module layer 12 may further include other metal layers or non-metal layers, which is not limited in the embodiment. It should be noted that in the top views of the display panel shown in FIG. 3 and FIG. 6, not entire film structure of the drive module layer 12 is illustrated. In order to obtain a clear relative relationship of the overlapping position between the auxiliary connection line and the jumper portion, only the source-drain electrode layer 128 of the drive module layer 12 is illustrated to characterize the position of the drive modules, and a relative positional relationship of the anode layer 15, the auxiliary connection line 15 a and the jumper layer 13 is illustrated.

With continued reference to FIG. 3, in an embodiment, the drive modules may be disposed in a matrix. The drive modules are disposed in rows along a first direction X, and the drive modules are disposed in columns along a second direction Y; and the first direction X intersects the second direction Y. The blocky anodes 15 b include a first blocky anode 152 b, a second blocky anode 153 b and a third blocky anode 154 b which are disposed in a triangle mode; the first blocky anode 152 b and the second blocky anode 153 b in a same triangle are disposed in a column along the second direction Y; and the drive modules connected to blocky anodes 15 b in a same triangle are disposed in a same row along the first direction X.

As mentioned above, FIG. 3 does not illustrate the complete structure of the drive module and only illustrates the source-drain electrode layer 128 including a data line 1281, a power signal line 1282, a source electrode 1201 and a drain electrode. Since the drive module is electrically connected to the blocky anode 15 b through the source electrode 1201, the position of the drive module may be characterized by the position of the source electrode 1201 in FIG. 3. As shown in FIG. 2, the source electrodes 1201 of all drive modules may be disposed in a matrix along the first direction X and the second direction Y respectively. The first direction X is used as the row direction, the second direction Y is used as the column direction, and the first direction X intersects the second direction Y. In an embodiment, the first direction X and the second direction Y may be disposed perpendicular to each other, so that the drive modules are disposed in a matrix, but in the embodiment, the blocky anodes 15 b are disposed in a triangle mode. In one embodiment, as shown in FIG. 3, the blocky anodes 15 b include the first blocky anode 152 b, the second blocky anode 153 b and the third blocky anode 154 b which are disposed in a triangle mode; the first blocky anode 152 b and the second blocky anode 153 b in a same triangle are disposed in a column along the second direction Y; and along the first direction X, the third blocky anode 154 b is disposed at a position between the first blocky anode 152 b and the second blocky anode 153 b, forming a triangle shape. Referring to FIG. 3, the source electrodes 1201 of the drive modules connected to the blocky anodes 15 b in a same triangle are disposed in a same row along the first direction X, that is, the drive modules connected to the blocky anodes 15 b in a same triangle are disposed in a same row along the first direction X. It should be noted that the first blocky anode 152 b and the second blocky anode 153 b are disposed in a column along the second direction Y. If the drive module of the first blocky anode 152 b and the drive module of the second blocky anode 153 b are disposed in a same row, one of the first blocky anode 152 b and the second blocky anode 153 b needs to be connected to the corresponding drive module through a strip-shaped jumper portion 131. For example, the second blocky anode 153 b shown in FIG. 3 is connected to the corresponding drive module through a jumper portion 131. In this embodiment, the jumper portion 131 is disposed, so that it is prevented that the second blocky anode 153 b extends a relatively long connection portion 151 b for being connected to the corresponding drive module, and the space of the gap region dl is saved. Moreover, an overlapped region between the auxiliary connection line 15 a and the jumper portion 131 exits, which is conductive to further increasing the width of the gap region dl between the blocky anodes 15 b to implement the layout of the auxiliary connection line 15 a and reducing the difficulty of the process of disposing the auxiliary connection line 15 a. In addition, the display quality is improved without sacrificing the pixel resolution while the width of the gap region dl is increased.

In an embodiment, with continued reference to FIG. 3 and FIG. 5, a jumper portion 131 may include a first end 1311 and a second end 1312; the drive module is connected to a first end 1311 of a jumper portion 131 corresponding to the drive module; the blocky anode 15 b is connected to a second end 1312 of a jumper portion 131 corresponding to the blocky anode 15 b; a first end 1311 of at least one jumper portion dose not overlap the blocky anode 15 b; a first end 1311 of at least one jumper portion 131 overlaps the blocky anode 15 b.

In this embodiment, the jumper portion 131 includes two connection ends connected to each other: the first end 1311 and the second end 1312. The drive module is connected to the first end 1311 of a jumper portion 131, and the corresponding blocky electrode 15 b is connected to the second end 1312 of the jumper portion 131, so that an electrical connection is established between the drive module and the blocky anode 15 b. As shown in FIG. 5, when the blocky anode 15 b is relatively far away from the corresponding drive module, the blocky anode 15 b may be connected to the corresponding drive module through an elongated jumper portion 131, so that a case where the first end 1311 of the jumper portion 131 does not overlap the blocky anode 15 b exits, that is, a case of the setting of the local region A1 exits. In addition, as shown in a local region A2 in FIG. 3, a case where the blocky anode 15 b is relatively close to the corresponding drive module exits in this embodiment, the drive module overlaps the blocky anode 15 b, so that the first end 1311 of the corresponding jumper portion 131 overlaps he blocky anode 15 b. In one embodiment, the first end 1311 of the jumper portion 131 may partially overlap the blocky anode 15 b, as shown in a local region A3 in FIG. 3. Of course, on the plane where the substrate 11 is located, the blocky anode 15 b may also completely overlap the first end 1311 of the jumper portion 131, as shown in the local region A2 in FIG. 3. In this embodiment, the arrangement of the blocky nodes 15 b may be adapted to the arrangement of the drive modules according to the arrangement of the subpixels in a triangle or a rectangle, so that the corresponding drive modules and the blocky anodes 15 b are connected through the jumper portions 131. Therefore, it is avoided that the blocky anode 15 b extends a relatively long connection portion 151 b, the area of the gap region dl is increased, the layout of the auxiliary connection line is facilitated, the difficulty of the process of disposing the auxiliary connection line on the display panel with the subpixels disposed in a triangle is reduced, the cathode potential is maintained to be stable, and the display quality is improved.

With continued reference to FIG. 2, in an embodiment, at least one blocky anode 15 b is electrically connected to a second end 1312 of a jumper portion 131, which is corresponding to the blocky anodes 15 b, of the jumper layer 13 through a first through hole K1 penetrating through the planarization layer 14. A vertical projection of the first through hole K1 on the plane where the substrate 11 is located is located within a blocky anode 15 b corresponding to the first through hole K1.

FIG. 2 is a sectional view taken along a segment C-C′ of the display panel in FIG. 3. As can be seen from FIG. 2, the blocky anode 15 b may be electrically connected to the second end 1312 of the corresponding jumper portion 131 through the first through hole K1 penetrating through the planarization layer 14. As can be seen from FIG. 3, the first through hole K1 is overlapped by the corresponding blocky anode 15 b on the plane where the substrate 11 is located, so that the first through hole K1 does not occupy the space of the gap region, which is conductive to implementing the layout of the auxiliary connection line in the gap region and improving the process quality of the auxiliary connection line.

FIG. 7 is a partial view of a top view of another display panel according to an embodiment of the present disclosure. In an embodiment, on the plane parallel to the plane where the substrate 11 is located, at least one blocky anode 15 b is a polygon. The vertical projection of the first through hole K1 on the plane where the substrate 11 is located is within a first connection region M1; and the first connection region M1 is a region, within the polygon, which is closest to the first end 1311 of the jumper portion 131.

Referring to FIG. 3 and FIG. 7, the blocky anode 15 b may be a rectangle. Of course, the blocky anode 15 b in the embodiment may also be rhombuses, circles, ellipses, polygons and the like, which is not limited in the embodiment. In an embodiment, as shown in FIG. 7, the blocky anode 15 b is a rounded rectangle, so that the manufacturing process is simple, rigid cracking is not easily to occur, and the quality of the manufactured panel is improved. As shown in FIG. 7, on the plane where the substrate 11 is located, the first through hole K1 is overlapped by the blocky anode 15 b, and the first through hole K1 is located within the first connection region M1 within the blocky anode 15 b. In this embodiment, the first connection region M1 is a region, within the polygonal blocky anode 15 b, which is closest to the first end 1311 of the jumper portion 131 in a straight line. The first through hole K1 is disposed in the above first connection region M1, so that the jumper portion 131 may further be disposed only in the first connection region M1, and the first connection region M1 is closest to the first end 1311 of the jumper portion 131 in a straight line. The length and area of the jumper portion 131 are minimized, capacitance between the jumper portion 131 and the anode layer 15 is avoided, thus the impact on the potential of the anode layer 15 is avoided, accurate dimming on the subpixels by the anode potential of the anode layer 15 is achieved, and the display quality is improved.

With continued reference to FIG. 3, as shown in the local region A2, in an embodiment, a vertical projection of at least one jumper portion 131 on the plane where the substrate 11 is located is located within the corresponding blocky anodes 15 b. In the way, on the plane where the substrate 11 is located, the first end 1311 and second end 1312 of the jumper portion 131 are overlapped by the corresponding blocky anodes 15 b, so that the first end 1311 and second end 1312 of the jumper portion 131 do not occupy the area of the gap region dl between the blocky anodes 15 b, thus the auxiliary connection lines 15 a can be arranged relatively dense, and the stability of the potential of the cathode layer 152 of the display panel is further improved. In addition, whether corresponding to the drive module or not, the blocky anode 15 b may be provided with a structure for being connected through the jumper portion 131, so that it is avoided that the resistance difference between different anodes and connection sections of the drive modules is too large, and the consistency of the electrical performance is effectively improved.

In an embodiment, the auxiliary connection line may further be used as an initialization signal line of the drive module. In order to form capacitance with the cathode layer, the auxiliary connection line needs to be connected to a fixed potential. Exemplarily, the auxiliary connection line may be connected to a zero potential or directly connected to a ground terminal of the display panel. In this embodiment, different fixed potentials may be selected for the auxiliary connection line 15 a, and the embodiment does not limit the specific potential. The drive module in the embodiment generally includes an initialization unit, a reset unit, a data write unit, a drive unit and a light-emitting control unit. The data write unit is configured to write a data voltage into the drive unit in a data write stage; the reset module is configured to provide a reset signal to a light-emitting element; and the drive unit is configured to drive the light-emitting control unit according to the data voltage. The drive module needs to be connected with a data line, an initialization signal line, a gate line, a light-emitting control signal line and the like. In the embodiment, the auxiliary connection line may be led to the drive module layer through a via to be used as the initialization signal line and be electrically connected to the initialization unit, so that the wiring arrangement of the drive module is saved, and the manufacturing process of the display panel is simplified.

FIG. 8 is a structural view of another display panel according to an embodiment of the present disclosure. In an embodiment, the display panel may further include an encapsulation layer 20 and a touch layer 21. The encapsulation layer 20 is disposed on a side of the cathode layer 152 facing away from the substrate 11; and the touch layer 21 is disposed on a side of the encapsulation layer 20 facing away from the substrate 11. The touch layer 21 includes a metal grid structure; on the plane parallel to the plane where the substrate 11 is located, the metal grid structure is disposed between the blocky anodes 15 b and overlaps the auxiliary connection line 15 a.

In this embodiment, the display panel may be a touch display panel, for example, a display panel in the form of a TPOT. As shown in FIG. 8, on the basis of the structure of the display panel in FIG. 2, the display panel may further be provided with the encapsulation layer 20 and the touch layer 21 sequentially on the cathode layer 152, and the touch layer 21 may include touch electrodes 211 disposed in an array, and the touch electrodes 211 in this embodiment may be composed of the metal grid structure.

In one embodiment, a touch electrode 211 includes multiple metal wires, and the metal wires cross each other to form metal grids. On the plane parallel to the plane where the substrate 11 is located, the metal grids are located between adjacent blocky anodes 15 b to avoid blocking the light emitted by the subpixels, that is, meshes of the metal grids corresponds to the openings of a subpixel definition layer. In addition, on the plane parallel to the plane where the substrate 11 is located, the metal grid structure at least partially overlaps the auxiliary connection line 15 a. In this embodiment, a vertical projection of the auxiliary connection line 15 a on the substrate 11 may be disposed to completely overlap the metal grid structure. Therefore, the auxiliary connection line 15 a serves as a metal shielding layer, so that the impact of the metal grid structure on a metal-material layer of the drive module layer can be effectively prevented. In addition, the auxiliary connection line 15 a in the embodiment may correspond to the path of the grid line of the touch electrode 211, which saves space and minimizes the parasitic capacitance between layers.

FIG. 9 is a top structural view of another display panel according to an embodiment of the present disclosure. In an embodiment, the auxiliary connection line 15 a may include multiple first auxiliary connection line segments 151 a extending along the second direction Y; and on the plane parallel to the plane where the substrate 11 is located, a first auxiliary connection line segment 151 a is disposed between adjacent two columns of blocky anodes 15 b. Adjacent two first auxiliary connection line segments 151 a are connected through a second auxiliary connection line segment 152 a; and on the plane parallel to the plane where the substrate 11 is located, the second auxiliary connection line segment 152 a is disposed between a first blocky anode 152 b and a second blocky anode 153 b which are adjacent to each other or between adjacent two third blocky anodes 154 b.

In this embodiment, the auxiliary connection line 15 a may include multiple first auxiliary connection line segments 151 a extending along a same direction, and adjacent two first auxiliary connection line segments 151 a may be connected through a second auxiliary connection line segment 152 a. As shown in FIG. 9, the first auxiliary connection line segment 151 a may extend along the second direction Y, and the first auxiliary connection line segment 151 a is disposed between adjacent two columns of blocky anodes 15 b. The second auxiliary connection line segment 152 a may extend along the first direction X and is disposed between adjacent two rows of blocky anodes 15 b. The blocky anodes illustrated in FIG. 9 are disposed in triangles. Therefore, on the plane where the substrate 11 is located, the second auxiliary connection line segment 152 a is disposed between a first blocky anode 152 b and a second blocky anode 153 b which are adjacent to each other, or the second auxiliary connection line segment 152 a is disposed between adjacent two third blocky anodes 154 b. The auxiliary connection lines 15 a shown in FIG. 9 have a simple layout structure, and the auxiliary connection lines 15 a are evenly distributed on the display panel, so that it is easy to form a uniform capacitive electrode layer on the entire plane parallel to the plane where the substrate 11 is located.

Referring to FIG. 10, FIG. 10 is a top structural view of another display panel according to an embodiment of the present disclosure. The blocky anodes 15 b may be rectangles shown in FIG. 9, or may be rhombuses shown in FIG. 10. The rhombic blocky anodes 15 b may further be disposed in triangles, so that the auxiliary connection line 15 a may include multiple first auxiliary connection line segments 151 a extending along the second direction Y. The first auxiliary connection line segments 151 a are disposed to match the rhombic blocky anodes 15 b and may be curvilinear as shown in FIG. 10, but the curvilinear first auxiliary connection line segments 151 a extend in a same direction. Moreover, in this embodiment, a second auxiliary connection line segment 152 a extending along the first direction X is disposed on an edge of the blocky anode 15 b. The second auxiliary connection line segment 152 a serves as a bus to connect the multiple first auxiliary connection line segments 151 a. The auxiliary connection lines 15 a shown in FIG. 10 have a simple layout structure, and the auxiliary connection lines 15 a are evenly distributed on the display panel, so that it is easy to form a uniform capacitive electrode layer on the entire plane parallel to the plane where the substrate 11 is located.

With continued reference to FIG. 3, in an embodiment, the auxiliary connection line 15 a may be a network structure; and a vertical projection of the blocky anode 15 b on the plane where the substrate 11 is located is located within a mesh of the network structure. The auxiliary connection line 15 a may be disposed in the gap region dl around the blocky anodes 15 b and form a network structure around the blocky anodes 15 b, so that the uniformity of the distribution of the auxiliary connection line 15 a is further improved, and the auxiliary connection line 15 a has a relatively large area directly facing the cathode layer, which is conducive to maintaining the stability of the cathode potential and improving the display efficiency of the display panel.

In an embodiment, with continued reference to FIG. 3, the anode layer 15, the organic light-emitting layer 151 and the cathode layer 152 may form a subpixel 153; and the display panel may include subpixels 153 of different colors; and on the plane parallel to the plane where the substrate 11 is located, at least part of subpixels 153 of a same color has a same first overlapped area; a first overlapped area of a subpixel 153 is an overlapped area of a jumper portion 131 and an auxiliary connection line 15 a within a same subpixel 153.

As shown in FIG. 3, the display panel may include multiple subpixels 153 of different colors. For example, the subpixels 153 may include red subpixels, green subpixels, blue subpixels and the like. For example, among the blocky anodes 15 disposed in a triangle mode provided by the above embodiments, the first blocky anode 152 b, the second blocky anode 153 b, and the third blocky anode 154 b may be sequentially used as a blocky anode of a red subpixel, a blocky anode of a green subpixel and a blocky anode of a blue subpixel. It can be seen from FIG. 5 that an overlapped area between a jumper portion 131 corresponding to the part of subpixels and the auxiliary connection line 15 a is S1. In this embodiment, the overlapped area between the jumper portion 131 of the subpixel 153 and the corresponding auxiliary connection line 15 a is defined as a first overlapped area, so that in the embodiment, the wiring of the auxiliary connection lines 15 a may be arranged to enable that at least part of the subpixels 153 of a same color has a same first overlapped area. Therefore, even if the capacitance between the auxiliary connection line 15 a and the cathode layer 152 has an impact on the emission brightness of the subpixels 153, for example, the emission brightness of the subpixels 153 is lower than a set value, since the subpixels 153 of a same color has a same overlapped area between the jumper portion 131 and the auxiliary connection line 15 a, the capacitance has a same impact on the emission brightness of the subpixels 153 of a same color, and the emission brightness may be compensated by adjusting gamma. In this way, the cathode potential is ensured to be stable, the error of brightness adjustment of the subpixels is reduced, and the color cast of the display picture is effectively avoided.

It should be noted that the above embodiments illustrate only the relative positions of the auxiliary connection line and the blocky anodes on the plane where the substrate is located, and do not limit the film layer on which the auxiliary connection line is disposed. In an embodiment, the auxiliary connection line may be disposed in a same layer as the blocky anodes, or may be disposed in a film layer between the blocky anodes and the cathode layer to form a capacitance with the cathode layer.

Referring to FIG. 3, the auxiliary connection line 15 a may be disposed in the anode layer, that is, the auxiliary connection line 15 a may be disposed in a same layer as the blocky anodes 15 b; a material of the auxiliary connection line 15 a is at least one of molybdenum or titanium; and a material of the blocky anodes 15 b is at least one of indium tin oxide or silver. In this embodiment, although the auxiliary connection line 15 a is disposed in a same layer as the blocky anodes 15 b, the metal material of the auxiliary connection line 15 a is different from the metal material of the blocky anodes 15 b. The material of the blocky anodes 15 b is at least one of indium tin oxide or silver, and the material of the auxiliary connection line 15 a is at least one of molybdenum or titanium. Therefore, two metal etching processes are required in the manufacturing process. In an embodiment, the auxiliary connection line 15 a and the blocky anodes 15 b may be separately formed by a wet etching process, and the auxiliary connection line 15 a is formed before the blocky anodes 15 b. For example, the blocky anodes 15 b may be made of an interlayer metal of indium tin oxide, silver and indium tin oxide, and the auxiliary connection line 15 a needs to be made of a metal insensitive to the above etching solution, such as at least one of molybdenum or titanium mentioned above. It should be noted that since the silver material in the blocky anodes 15 b is easily corroded and oxidized, a metal film layer of molybdenum and titanium is formed first, and then the metal film layer is subjected to wet etching to obtain the structure of the auxiliary connection line 15 a; thereafter, an interlayer metal of indium tin oxide, silver and indium tin oxide may be formed, and then the shape and structure of the blocky anodes 15 b may be etched by an etching solution. Since the etching solution should not affect the auxiliary connection line 15 a, the material of the auxiliary connection line 15 a should be different from the material of the blocky anodes 15 b, so that a metal insensitive to the etching solution, such as molybdenum, titanium mentioned above and the like, is required. In the embodiment, different procedures are adopted for the auxiliary connection line 15 a and the blocky anodes 15 b through two metal etching processes, so that the size of the auxiliary connection line 15 a, such as the line width, and the size of the blocky anodes 15 b and the like may be adjusted in the separate procedures. For example, the line width of the auxiliary connection line 15 a may be set to be slightly wider, or the area of the blocky anode 15 b may be set to be relatively large. Through the above two-time metal etching process, the room for the adjustment of the processes of the auxiliary connection line 15 a and the blocky anodes 15 b is increased, which is conductive to achieving the rational layout of the auxiliary connection line 15 a and the blocky anodes 15 b.

With continued reference to FIG. 3, the auxiliary connection line 15 a may be disposed in a same layer as the blocky anodes 15 b, and the material of the auxiliary connection line 15 a is the same as the material of the blocky anodes 15 b. In the embodiment, the auxiliary connection line 15 a and the blocky anodes 15 b may also be manufactured by a same process, and thus the material of the auxiliary connection line 15 a is the same as the material of the blocky anodes 15 b. Exemplarily, at least one of indium tin oxide or silver may be used. In the embodiment, through the process of disposing the auxiliary connection line 15 a and the blocky anodes 15 b in a same layer, one metal etching process can be saved, the manufacturing process of the display panel can be simplified, and the manufacturing efficiency of the display panel can be improved. As shown in FIG. 5, in the embodiment, a distance between an edge of the auxiliary connection line 15 a and an edge of an adjacent blocky anode 15 b is less than or equal to 5 μm. Due to the setting of the jumper layer 13, the setting of the connection portions 151 b of the blocky anodes 15 b may be greatly reduced, the space of the gap region dl is saved, and the width CD1 of the auxiliary connection line 15 a may be set relatively large than that of a display panel without disposing the jumper layer 13. In one embodiment, if the distance between adjacent blocky anodes 15 b is larger than 13 μm, the distance between an edge of the auxiliary connection line 15 a and an edge of an adjacent blocky anode 15 b is controlled to be less than or equal to 5 μm to prevent a case of a short circuit or an open circuit. Referring to FIG. 6, no jumper layer is disposed in FIG. 6, so that the width CD1′ of the auxiliary connection line 15 a′ is less than the width CD1 of the auxiliary connection line 15 a. Compared with the comparative example shown in FIG. 6, in this embodiment, the width CD1 of the auxiliary connection line 15 a may be increased to multiple times, so that the difficulty of the manufacturing process of the auxiliary connection line 15 a is reduced, the auxiliary connection line 15 a is prevented from being broken during the manufacturing process, and the reliability of manufacturing the display panel is improved.

In addition, the auxiliary connection line 15 a and the blocky anodes 15 b may be respectively disposed in different film layers. FIG. 11 is a structural view of another display panel according to an embodiment of the present disclosure. In an embodiment, the display panel may further include a pixel definition layer 17 and a support pole 18. The pixel definition layer 17 is disposed between the anode layer 15 and the organic light-emitting layer 151; the support pole 18 is disposed between the pixel definition layer 17 and the organic light-emitting layer 151; and a vertical projection of the support pole 18 on the plane where the substrate 11 is located is located within the pixel definition layer 17. The auxiliary connection line 15 a is disposed between the pixel definition layer 17 and the support pole 18; and the vertical projection of the support pole 18 on the plane where the substrate 11 is located completely overlaps the auxiliary connection line 15 a. The auxiliary connection line 15 a is disposed between the pixel definition layer 17 and the support pole 18, so that the blocky anodes 15 b and the auxiliary connection line 15 a can be effectively isolated, and mutual impact between signals of the blocky anodes 15 b and signals of the auxiliary connection line 15 a is avoided.

In addition, as shown in FIG. 12, FIG. 12 is a structural view of another display panel according to an embodiment of the present disclosure. The auxiliary connection line 15 a may further be disposed in a different layer from the blocky anodes 15 b. The auxiliary connection line 15 a may be disposed in a conductive layer on a side of the blocky anodes 15 b close to the substrate 11. The blocky anode 15 b avoids the auxiliary connection line 15 a through the connection portion 131, so that it is avoided that an overlapped area between the blocky anodes 15 b and the auxiliary connection line 15 a exits on the plane where the substrate 11 is located and that signals of the blocky anodes 15 b and signals of the auxiliary connection line 15 a affect each other.

Referring to FIG. 3 and FIG. 11, the display panel may further include the pixel definition layer 17 and the support pole 18. After the anode layer 15 is formed, the pixel definition layer 17 is disposed on a side of the anode layer 15 facing away from the substrate 11, and the support pole 18 is disposed on a side of the pixel definition layer 17 facing away from the substrate 11, and a vertical projection of the support pole 18 on the plane where the substrate 11 is located is located within the pixel definition layer 17. Then, the organic light-emitting layer 151 and the cathode layer 152 are sequentially disposed on a side of the support pole 18 facing from the substrate 11. As shown in FIG. 3, the auxiliary connection line 15 a is disposed in the anode layer 15, and in the embodiment, the auxiliary connection line 15 a is disposed on a side of the anode layer 15 close to the cathode layer 152. As shown in FIG. 11, the auxiliary connection line 15 a may be disposed between the pixel definition layer 17 and the support pole 18, and the support pole 18 may completely overlap the auxiliary connection line 15 a to achieve the insulation between the auxiliary connection line 15 a and the cathode layer 152. In this way, the auxiliary connection line 15 a and the cathode layer 152 form the capacitance to stabilize the cathode potential. Moreover, due to the setting of the jumper layer 13, the setting of the connection portion 151 b in the gap region dl on the anode layer 15 is greatly reduced, and the auxiliary connection line 15 a overlapping the jumper layer 13 is not disposed in the anode layer 15, so that the size the blocky anode 15 b may be appropriately increased according to the size of the gap region dl, and increasing the light-emitting area of the entire display panel is increased and the flat display ration of the display panel is increased.

In an embodiment, a distance between an edge of the auxiliary connection line 15 a and an edge of the pixel definition layer is less than or equal to 3 μm. Since the auxiliary connection line 15 a is not disposed in the anode layer 15, the size of the auxiliary connection line 15 a may be set as wide as possible on the premise that the size of the auxiliary connection line 15 a is less than the width of the gap region dl between the blocky anodes 15 b. For example, the projection of the auxiliary connection line 15 a may partially overlap the blocky anodes 15 b, so that the area directly facing the blocky anode 15 b and the cathode layer 152 is increased, the capacitance between the auxiliary connection line 15 a and the cathode layer 152 is increased, and the stability of the potential of the cathode layer 152 is improved.

Compared with the display panel in the comparative example, according to the display panel provided in the embodiment, the setting of the connection portions of the blocky anodes in the anode layer 15 can be reduced, which is conducive to disposing the auxiliary connection line 15 a in the gap region between the blocky anodes to form stable capacitance with the cathode layer. Therefore, the display quality of the display panel is improved, and the touch accuracy of the display panel integrated with a touch function is improved.
